## ts2avi version 1.03 (01/11/2012) freeware by robert_maul@hotmail.com
## translate *.ts to *.avi (XviD) (works well with avidemux editor)

## ALERT: Version 1.02 broken by WinFF Version 1.4.0 (see notes below)
## this script will break again with the next version of WinFF

## This script runs on Windows using MinGW Shell aka Msys (Minimal Gnu on Windows)
## which is downloaded from sourceforge.net (cygwin has no uninstall! too messy!)
## since i started using MinGW i don't bother with Ubuntu any more.
## I added this script to my c:\users\robert\bin directory and
## that directory to the end of the system PATH variable

JAVA_HOME="/c/Program Files/Java/jre7/bin" # 64 bit java install
java="$JAVA_HOME/java"
projectx="/c/Project-X_0.91.0/ProjectX.jar"
FFMPEG_HOME="/c/Program Files (x86)/WinFF" # 32 bit (WinFF)
#FFMPEG_HOME="/c/AutoFF0998_Full_win" # 32 bit (AutoFF)
ffmpeg="$FFMPEG_HOME/ffmpeg"
AVIDEMUX_HOME="/c/Program Files/Avidemux 2.5"
avidemux="$AVIDEMUX_HOME/avidemux2_cli" # 64 bit command line version

## download locations: (i use 64 bit when available on my 64 bit machines)
##
## java: http://download.oracle.com/otn-pub/j...indows-x64.exe
## project-x: http://sourceforge.net/projects/proj...urce=directory
## avidemux: http://avidemux.sourceforge.net/ (choose command line when installing)
## ffmpeg: http://www.videohelp.com/tools/ffmpeg (then choose AutoFF link)
## or
## ffmpeg: http://www.winff.org/html_new/downloads.html
##
## email me suggestions for stable 64 bit version of ffmpeg that is easy to install.
## of course it would be nice if you tested it with this script before emailing me.

## Changes for 1.01: adjusted numbers for -wide2full option
## ffmpeg docs for -cropleft and -cropright very confusing.
## only took me about 1 year of tying different things to figure this out!

## Changes for 1.02: added -full2wide option for non HD station airing widescreen
## video (tiny widescreen rectangle in the middle of widescreen monitor)
## adjusted numbers for -full option so no resizing happens, (faster translation)

## Changes for 1.03: This script was broken with WinFF version 1.4.0 (works with WinFF 1.3.1)
## I don't know why the ffmpeg command line option changed but I have attempted temp fix

## Old Linux based notes:
##
## Ubuntu Linux version depends on project-x, winff and
## libavcodec-unstripped-52 # the name of this lib may vary but it contains XviD
## all found in ubuntu 10.10 synaptic repositories
## also depends on avidemux2_cli listed as avidemux-cli in rep

## i have a haupaugge capture card that creates the *.ts files
## i am currently looking for a better card since the WinTV
## software that comes with it crashes all time with the 2250
## so i had to yank it run with my old 1600 card only.
## UPDATE: WinTV 2.4 has not crashed on me yet.

## I imagine that this script could be adapted to convert the
## video files created with other brands of cards. suggestions
## for new cards greatly appreciated

## windows users can install ubuntu on there windows box quite
## easily using virtualbox 4.x and ubuntu.10.10 ... i found it
## easier than trying to rewrite this script in a windows script
## virtualbox lets you run windows and ubuntu linux at the same time

## my next project is to write a cron script that will run this
## this script automattically and delete the large ts and m2v
## files and leave just the *.avi and *.ac3 files that need to
## be merged before editing. so as the large ts files are
## created they can be tranlated to xvid unattended

## as of version 4.0 of virtualbox it is easy to share folders
## between the host (windows) and guest (ubuntu) machine provided
## that the share is not on the C: drive (permissions problems)

## note: the final *.editing.avi files created by this script will
## be larger when run through project-x, you can get away without
## running project-x if the input files have no bad data.
## bad data is usually weather or signal strength dependent.

## step 1 (automated)
## use Project-X to throw out any bad data and sync video and audi0
## with ProjectX (free download at sourcforge.net)
## for each ts file create a directory and move the file there.
## then demux the file creating the m2v (video) and ac3 (sound)
## The Project-X command line method was found in the ProjectX
## source ReadMe.txt file

## step 2 (automated)
## create avi file using ffmpeg (download winff and ffmpeg included)
## translate the m2v (video only) file to an avi (XviD) file
## the ffmpeg options used here were found by running winff and
## choosing: "Display CMD Line" under the options menu

## step 3 (automated) avidemux command line is run to put the *.avi
## and *.ac3 (audio) files together to create the *.editing.avi

## step 4 (manual)
## edit out commercials with avidemux and save that file as:
## *.done.avi

arg=$1
crop=""
if [ $arg = "-wide" ]; then
dim=704x384 # Winff default value used in case user wants to run 2-pass on
asp=16:9 # final edited *.done.avi file using WinFF (might make it smaller)
echo running with widescreen $asp aspect ratio $dim resolution
else
if [ $arg = "-wide720p" ]; then # disk space is getting cheaper so save quality
dim=1320x720 # 16/9=x/720 solve for x=1320
asp=16:9 # 720p just means vertical resolution is 720
echo running with wide screen 16:9 aspect ratio 720p resolution
else
if [ $arg = "-wide2full" ]; then # for HD station with full screen video
echo running with wide to full screen cropping to 4:3 aspect ratio
asp=4:3 # assuming the mpeg-2 file is 1980x1080 1980/16=x/4 solve for x=495
crop=" -cropleft 246 -cropright 246 " # 495/2~=246 (must crop in even numbers)
# 246 + 246 + 640 = 1132 (add back what was cropped off to arrive at 640x480)
dim=1132x480 # cropping happens before resizing but it also affects the
# resolution after resizing so it must be added back (very weird)
else
if [ $arg = "-full2wide" ]; then # for non HD station with wide screen video
echo running with full to wide screen cropping to 16:9 aspect ratio
asp=16:9 # assuming the mpeg-2 file is 704x480 704/16=x/9 solve for x=396
crop=" -croptop 42 -cropbottom 42 " # 480-396=84 84/2=42
dim=704x396 # no resizing, just cropping
else
if [ $arg = "-full" ]; then
dim=704x480 # no resizing = faster translation
asp=4:3
echo running with fullcreen 4:3 aspect ratio $dim resolution
else
echo args must be: "-wide", "-wide720p", "-wide2full", "-full2wide" or "-full"
